To all whom it my concern:

Be it known that I, HERBERT L. v GLAZE, a

Angeles, in the county of s Angeles and State of California, have invented; new and useful Improvements in Material-Mixers, of wh' h the following is a specification.

two whic y invention relates-to means for mixing 7 both wet and dr materials and particularly to a form of device which may be applied for domestic and industrial use, the main object being to provide means adapted to be op-V erated in a bowl, cylinder, housing or any form of container, whereby the materialsv 15 may be thoroughly mixed and the surfaces of the .container and of the. mixers proper are 'thoroughly scraped and kept clean during the mixing operation. i

I have discovered that a plurality of like wiping members rotating in the samedirection and composed of prisms generated'by' the longitudinal movement of identical plane figures will remain in perpetual contact peripherally, some point on the periphery of one of said elements being always in contact with somepoint on the periphery of the other element, each element or plane figure consisting of two segments of circles with coincident chords, said figures rotating around chord centers, the distance between whichcenters is. equal to the square'roo't of one half the square of the chord and the radius of each segment being equalto the center distance. i 1

It is an object, therefore, to provide in a device of the character referred to, a mixing machine having a plurality of wiping elements each composed of two segments with a common chord, having spaced axes of rotation and intersecting arcs and adapted to be rotated in a single direction, for the purpose stated.

I accomplish the above and other objects by means of the mechanism illustrated in the. accompanying drawings, forming a part of this application, in which, similar characters of reference are employed for indicating the same and like parts.

In said drawings I have illustrated two separate and distinct applications showing ractical embodiments of my invention h may be adaptable to domestic or industrial uses as desired, any modification thereofdepending upon the character of the work desired to be accomplished:

1 standard 1 is provided with abase 2. A

,ard, a bevel :gear 6 bein bearing 13, and has a 'cylindrlcal interior Shaft 14 has a gear '24 on the upper end Figure 1 is a plan iew of one form of mix- I l ing machine adapted for use domestically citizen of the Umted States residing at Los 1 to 3, is employedand enlarged upon,

Fig. 5 is a side elevation of the same,

Fig. 6 is a fra entary sectional, elevation ofthe same, and t i r Fig. 7 is adiagram of the wipers shown in Fig; 4, showing different relative. positions of the individual wi ers.

Referring first to igs. 1 and 2, as'uitable vertical shaft 3 is housed in @the standard 1 andhas bearings at 4 and;5, in the standcarried on the lowerend of said shaft w ich meshes with and isadapted to be driven by a, Similar gear 7 on aihorizontalshaft 8. v Shaft 8'has bearings at, 9 and 10 in'the standard and carries a pulley 11 on its outer end by means of "which the machine maybe operated from any suitable source of power.

A bracket 12 ,is provided onvthe standard 1, and has a bearing 13 on the outer end thereof in which a vertical shaft 14 is journaled. A bowl, or container 15, is loosely held on shaft 14jagainst the upper end of chamber .16 and an exteriorv spur gear 17 .thereon which is adapted to mesh witha.

pinion 18 carried on shaft 3 above the main bearing 4. c

The extreme upper end of main shaft 3 has a large gear 19 thereon,-which is spaced from pinion 18 by means of a bracket 20, which is extended outwardly from the standard 1 and serves as a support for the upper endof shaft 14, a bearing 21, being rovided on said bracket for said shaft.

racket 20 is attached to an arm 22 of the standard 1 by means of bolts 23, 23, and isthus held stationary during the operation of the gears.

thereof, which meshes with and is driven by the large gear 19, and bracket 20 has I another be'arin 25 which is'radially alined with the axis 0 shaft 1'4 and has a shaft 26 held therein. A gear 27 of like size and character as gear 24, on shaft 14 is provided on shaft 26 and this gear is also meshed with and is driven by the large gear 19. Thus shafts 14 and 26 are rotated in the. same direction and at equal speed through the medium of the connections described. 1

The lower end of the shaft 26' and the central portion of shaft 14 areeach provided with a wiping element W, each of said elements being composed of a pair of like peripheral portions 28, which are true segments of acircle of an equal radius and the chords of whose arcs are coincident. Thus, the major diameter, or the chordof one of the segments plus one half the minor diameter of one of the elements, or the hei ht of one of the arcs, will equal the radius, of the interior of the bowl 15, the spacing of the axes of shafts 14 and 26 bemg the same as the radius of one of the se cuts of the wiping elements.

rom' Fi 2, it will be observed that the bowl 15 wil rotate at a slow speed, while the wipers will rotate at a relatively high speed, and the peripheries of the wipers will always be in contact, while the bottoms thereof will contact with and serve to Wipe .ghe bottom 30of the bowl. The top of the 80 0W1 may be open as shown, or-a suitable cover may be provided. It. will be seen that material placed in the bowl will be continuously stirred u and moved about. A complete mixture 0 the ingredients results, the surfaces of the contributing mixing elements beingat the same time wiped and scraped free from an surplus quantities of the 'mixture, thus 0 viatlng the frequent cleaning of the machine. i v I Now, referring particularly to Figs. 4 to 8, in whicha multlple machine is shown, 31

- 1s a frame upon which an elongated container 32 is mounted 'and which has a plurality of mixing compartments 33, 33', etc.,

. an arm 37,

a feed chamber or inlet 34, and an outlet chamber 35. Each chamber 33 has a vertical shaft 36, journaled in the bottom thereofand extendedat the top and journaled in provided with a pair of bearings 39 and .39, the said arms being attached to one side ofthe container 32. Each of the shafts 36 hasa bevelend thereof, which is driven by a similar gear 41, on a longitudinal shaft 42, extendmg above the container 32, and supported near its ends in bearings 43, 43, shaft 42 may be rotated or drivenvfrom any suitable source of power by means of a belt pulleys 44, or otherwise. Two shafts 36, have the wipers-W on the lower portions thereof and are of the character and form previously described, the bottoms of the Wipers scraping the floor of the container 32, and the polnts thereof scraIping the arcuate walls of the container. t will be observed that same result when tions.

the se gear 40 on the upper full length of the container along one side i and returned along the other side by the action of the wipers, after which the mixture will be discharged at the outlet 35.. This form of machine may also be used as a conveyer, as the rotation of the wipers in like direction serves to move the body of thevmixture lengthwise of the container, and by ap-,'

plying heat to the container, material may be dried therein whilein motion. The uses for my device are many and I have sought engagement of the wipers. 'Itwill be obvious that the wipers will not produce the operated in opposite direc- What I claim is: 1. A mechanical movement embodying a plurality of arcuate elements rotatable in like directions, whereby their peripheries *may be maintalned in continuous contact.

2. A mechanical movement embodying a plurality .of elements, the opposite peripheral portions of said elements being arcuate and having equal radii, s id elements being rotatable in like di'rectio whereby 3. A mechanical movement including a pair of rotatable elements having two seg- 'only, to illustrate two applications of, a

principle which I believe to be new, namely,

6. A mechanical movement includinga plurality of continuously contacting. rotatable elements having spaced axes and rota table in like direction, said elements having 'two segmental portions with common chords and'the distance between their axes being.

equal to the square root of one' half the square of the chords and also equal to the radius of each segment.

7. A device of the character described,

of continuously contacting rotaand of equal radius, the major points on said elements operating in intersecting arcs and the center distances between said elements being equal to the radius of each of said arcuate portions. 7
